WEELDER,

Application tiled September 225,A 1926. Serial 17051322794.

This invention relates'to new and useful improvements in agricultural n'iachines, and particularly to cultivators.

The principal object of the invention is to provide' a novel and improved form of weeder which is adapted to be connected with the ordinary cultivntor.

Another object is to provide a device of this character which is adapted to dig out the weeds between the plants of n. row, While at the same time, the regular cultivator shovels stir the soil at the sides of the row. such action of the Weeder being performed Without injury to the standing plants.

Other objects and advax'itnges will be npparent from the following' description when taken in connection with the aecoinpai'iying drawings.

In the drawii'igs:

Figure l is a top plan view of a portion of e. cultivator, 'showing the invention applied thereto.

Figure 2 is a rear elevation of the same.

Figure 3 is an enlarged view showing the manner of connecting the 'draw hars to the tooth bars of the cultivator.

Figure Il is an enlarged longitudinal scc' tional view through the Weeder wheel and the hub thereof.

Figure 5 is s. perspective view of the reni' connected ends of the draw bars, showing the manner of mounting the axle ot' the weeder Wheel thereof, and the means 'for aceornplishing the adjustments ot the wheel.

Figure 6 is a top plan view of the clamp shown in Figure 3.

Referring particularly to the accompanying drawings, l represents the tooth bars of e. cultivator of the siraddle rov.' type. euch bar having 'the stems ll, of the -nltivator shovels 12 properly clamped thereon.

Properly embracing each of the foremost of the shovel stems 1l is a two-piece clamp 13, having a lateral arcuate lug 14, which is.

formed with a fiat portion 14. Enga red on this flat portion 14', is one end of a ar l5, said bar having openings receiving the legs oi. a U-bolt 1G, which is engaged around said lng, and having nuts on said legs, Wherehy to llrinly elem the bar end on the lug. The. other ends o the bars l are disposed in superimposed relation, und provide-d with registering openings. Disposed on the upper har 15,over the apertured end, and provided with a transverse groove l?, receivhigaportion of seid bar end, is a disk 18, also having a central opening registering with theiopenings of the bars. The upper iaee of the disk is provided with radial ribs and grooves 19, with which are meshed the ribs and ooves of a second disk 201 disposed on the dlisk 18. This upper disk is formed with a vertical peripheral flange 2l, and in this flange are the series o notches 22, said upper disk being thinner at one side than at the other. Disposed through the registering openings of the hars lo, and the' threaded stein 23, the lower end of which carries a nut 24, While the u per end is formed with an angular eye 25, fljir a purpose which will now be described.- A shaft 26 is disposed through the eye 25, while the remainder ot' the shaft, which is circuler in cross section, is disposed through an axle skein 27. A Washer plate 28, ht/ing a pe ripheral flange embracing the larger end of the skein, is disposed on the said shaft, beneuth the nut 26', thereof, as clearly seen in the sectional view Figure 4.' A similar washer plate 2li is engaged on the other orV smaller end of the skein, and has afiange embracing said end of the skein5 and a ceiilral opening receiving the shaft there through. `Rotatably supported on the skein is the hub 30, which has a Jeripheral flange 3l, in one side face of which are formed the radially extending grooves 32, and disposed in each of these grooves is a radially extending spoke The outer side of the inner end ot cach of the spokes is formed with an enlargement 34', which is received .in the circular groove 'formed in the face of the renining disk 3G, said disk being slipped ionto the hubq and held in spoke clamping position by. bolts ot rivets passed therethrough and through the flange of the hub.

It will be noted that the clamp 13 coinprises two L-shuped members i3', each of which has an opening in one end for the reception of the threaded end of the other member, a nut ifi being engaged thereon, whereby1 seid clamp is capable of. properly embracing posts of different sizes.

By means of the disks 18 and 20, and the clamping member 23, the Wheel, including the hub 30 and spokes 33, may be swung in a horizontal plane, whereby to dispose the same at different anglesv with respect to the line of draft of the cultivator. The Wheel is mounted to lie between the angs of eultivator teeth or shovels, @ng to, operate disks 18 and 20, is a is formed with an angular end portion which I transversely of thelrow et pin-nte, end heilig' up between the plants of the row. This ec- 1tion of the wheel wiilalso stir up the soil close to the plants, et points not reached hy 'the cultivator ehovels it will also be noted that, hy ineens ,of the wie or shaft ot" the wheel., sind the beveled or inclined upper disk fdl), with 'its notched 'ange which receives adiacent ,portion et the shaft., the angle o the wheel with respect to a vertical plane, nlny he varied, and thereby regulate the of] th to which the spokes o the Wheel will 'dig into the soil. Also, this action of the Weeder Wheel serves 'to properly mulch 'the plainte.

The eye is provided with e set screw 23'? .which is arranged yto engage the square portion of the shaft; 26, to hold the sanne in diterent adjusted positions therethrough. -ihe Suid square portion of the shaft is of greater dinmeter than the cylindrical portion whereby `to forni si, shoulder 39, for engegemet with the washer plate 29.

id he noted thee the inge 1d are ereno'e wnherehy to permit the bars 15 to "proporly engage therewith, regardless ot the .ongle et which they extend with relation to each other. The outer ends of the lugs 14 ere apertured to receive the cotter pins 38.

'What is claimed is:

A. Weeder attachment for a cultiyetor coinprising a pair of rearwardly converging bars, clamps for engagement on certain of the shovel standards of the cultivator and each having e lug projecting from one side thereof, the forwnrdend of each ot the seid bars being clamped on a lug, u disk arranged on the converged ends oi' the said bars, a second disk rotatably adjustable on the first disk, said second disk having a notched hinge on its upper portion, n bolt disposed vertically through the disks and smid converged ends oi' the hairs, a nut engaged on the holt beneath the bars, the upper end of the holt having an angular eye, an angular shaft disposed through said eye und rest-ing in u notch of the upper disk, and a Weeder wheel rotatably mounted on said shaft..

in testimony whereof, l alibi iny signature.
